I applied through an employee referral. The process took 2 weeks. I interviewed at Checkout.com (Berlin) in Feb 2021
Interview
Pretty smooth process with different people. TA, Product lead, and 2 engineering leads. Very nice "casual" conversation, product dep dive with the Product lead, and more workflow relationship with the Engineering leads.
Interview process less than 2 weeks, pretty quick regarding the number people I had to interact with.
